+Double-buffer shadow updates. When enabled, the driver will keep two copies of
+the shadow framebuffer. When the shadow framebuffer is flushed, the old and new
+versions of the shadow are compared, and only tiles that have actually changed
+are uploaded to the device. This is an optimization for server-class GPUs with
+a remote display function (typically VNC), where remote updates are triggered
+by any framebuffer write, so minimizing the amount of data uploaded is crucial.
+This defaults to enabled for ASPEED and Matrox G200 devices, and disabled

    We don't support 8bpp, and we do have acceleration.

 .SH DESCRIPTION
 .B modesetting
-is an @xservername@ driver for KMS devices.  This is a non-accelerated
-driver, the following framebuffer depths are supported: 8, 15, 16, 24.
-All visual types are supported for depth 8, and TrueColor visual is
-supported for the other depths.  RandR 1.2 is supported.
+is an @xservername@ driver for KMS devices.  This driver supports
+TrueColor visuals at framebuffer depths of 15, 16, 24, and 30. RandR
+1.2 is supported for multi-head configurations. Acceleration is available
+through glamor for devices supporting at least OpenGL ES 2.0 or OpenGL 2.1.
+If glamor is not enabled, a shadow framebuffer is configured based on the
+KMS drivers' preference (unless the framebuffer is 24 bits per pixel, in
+which case the shadow framebuffer is always used).
